GPIO Multi-Muxed option

Mohamed,

Please try to download and use pixmux utility from our landing page:

I mean that there are some GPIO pins that multi-muxed.

Is there any configuration to select which pin i need to use except the PINCTRL register?

I can't use GP1[7] on pin w1 but i can use it on pin w6, this is my problem.

Hi,

You need to set PINCNTL7 register to use GP1[7] on W6. But when you do that you should disable the GP1[7] functionality on W1. It is not correct to use same functionality on two different I/Os simultaneously.

Team,

I revive this thread as I dont think the problem is that GP1(7) was configured simultaneously on W1 and W6, but I wonder if GP1(7) can be configured at all as GPIO on W1. I have that problem today (ie I cant configure GP1(7) as GPIO on W1).

Can you specifically test this?

Hi.

There seems to be a mistake in the link...

Thanks.

Hi it would be good if we could read this link as i am having the same problem configuring GP1[7] on pin W1

Hi Mathew,

I just test the link and it works just fine.  Can you try again?

Hi the link does not work for me unless you change it to:

http://e2e.ti.com/support/dsp/davinci_digital_media_processors/f/716/t/153934.aspx

ie remove the /int-dm814x/
